Monitor system health using CloudWatch dashboards, alarms, logs, metrics, and X-Ray tracing, responding to issues and recommending improvements. Maintain and evolve AWS infrastructure using CloudFormation, AWS SAM, and Terraform. Build, update, and support TypeScript-based Lambda functions, APIs, and microservices. Improve platform reliability, performance, and resilience through automation and DevOps best practices. Enhance and run CI/CD pipelines (GitHub Actions) with automated testing and deployment. Containerise where needed using Docker for local development and ECS workloads. Apply strong security, operational readiness, and GDS-aligned standards across the platform.Essential Skills & Experience Strong experience supporting and troubleshooting cloud-native applications in AWS. Deep knowledge of Lambda, API Gateway, CloudFormation, Terraform, and general AWS serverless patterns. Proficiency with TypeScript/Node.js for operational fixes, enhancements, and service updates. Solid understanding of platform monitoring (CloudWatch logs, metrics, alarms, dashboards, tracing). Experience building and maintaining IaC pipelines and CI/CD workflows. Comfortable working in a DevOps-style environment — automation-first mindset, operational ownership, and incident/problem-solving capability. Experience in government or GDS-aligned digital services is highly beneficial. Strong communicator able to work with product, ops, and engineering teams to resolve issues quickly
